The present Invention Privilege Patent relates to a device for dryinghair with provision of air flow with driven air jets, wherein suchdevice uses as source of provision of air flow (heated or not) aconventional electric hair dryer.

The present Invention Privilege Patent also relates to an electric hairdryer with provision of air flow with driven air jets, which is based onthe concept of the device above described.

As it is generally known, hair dryers are widely used appliances, bothfor domestic use and in beauty parlors and similar businesses.

In summary, hair dryers are appliances promoting the creation of aconcentrated air flow, which can be either in room temperature orproperly heated by a heating element as an electric resistanceinternally assembled to the appliance, which the air flow is mandatorilyforced through.

Presently, hair dryers are basically divided into two types, one ofwhich is represented by handheld hair dryers, while the other type isrepresented by the appliances known as standing hair dryers.

Handheld hair dryers, despite the wide range of models and variations,are defined by an essentially tubular body, where the air is sucked bythe posterior opening and is blown by the frontal opening, wherein theblow dryer internally embodies a motor/rotor set and an electricresistance set, as well as the actuation keys that are positioned in ahilt.

On the other hand, standing hair dryers also comprise a motor/rotor setand also one or more electric resistances, differing from manual modelsby the fact that such components are arranged in a body that isdeveloped to take a shape of a dome, inside which the users' head mustbe placed.

Said dome is normally defined by a transparent coverage that creates aheating chamber that involves the user's head.

The dome of the above mentioned model is attached to a vertical standthat is why the phrase “standing hair dryer” is used to define suchappliance.

The state of art is defined by a large number of models of both hairdryer types, which do not basically in terms of project solution.

Regarding standing hair dryers, it is possible to notice that the airflows (normally hot), vertically goes down from the upper part of theappliance and tends to occupy the chamber inside which the user's headis placed.

This type of solution is not totally appropriate since the heat,although propagated by air flow, does not manage to penetrate into hairbody, especially in case of very long hairs or excessively dense.

The present state of art, parallel to above described hair dryers,foresees a type of accessory that, applied to a handheld hair dryer,allows directing the air flow in a punctual fashion, if, for example,from the device addressed in patent application PI 0603255-9, filed on 4Aug. 2006 and having as title “ACCESSORY FOR USE IN CONJUNCTION WITHHAIR DRYERS”.

Even though said accessory presents advantages regarding conventionalhandheld hair dryers, it is neither indicated nor to be used withstanding hair dryers.

So, a solution was developed aiming at reducing such issues and proposesa new project solution for standing hair dryers, wherein the classicembodiment defining said heating chamber was abolished.

The present invention privilege patent relates to an appliance developedto dry up hair, which operates according to the provision of air flowwith driven air jets, said appliance can be used in conjunction withconventional electric hair dryers. The present patent also relates to avariation of such appliance, wherein it is embodied as hair dryer withprovision of air flow with driven air jets.

The solution proposed by this invention privilege patent allows the airflows produced in the form of driven air jets may create conditions forpenetrating even into dense or big hairs.

The present patent will be now described in detail with reference to thedrawings below, wherein:

FIG. 9 illustrates a variation of the hair dryer addressed in FIG. 8 andconsisting of a variation of the device for drying hair, such aspresented in FIGS. 1-7.

In conformity with the illustrated Figures above related, the presentinvention privilege patent proposes a device for drying hair 1 which isassembled in a vertical stand 2, being said vertical stand 2 inferiorlyprovided with a base 3 provided with casters 4.

The device for drying hair 1 is set as a basically hollow structure 5,which is provided in its upper portion with a nozzle 6 which is orientedto receive, by simply fitting, the nozzle of a manual hair dryer ofconventional type 7, as can be understood by observing FIG. 1.

FIG. 2 depicts an amplified view of FIG. 1, where drying appliance 1 canbe more clearly seen.

Said device for drying hair 1 may, alternatively and in substitution ofvertical stand 2, be provided with a support 8 which allows the fixationof said device for drying hair 1 in a wall or other appropriate support.

Both in the version applying vertical stand 2 and the one applyingsupport 8, the structure 5 of the device for drying hair 1 comprises aposterior projection 9, from which a coupling terminal is developed 10,wherein, by simple fitting, both upper end of the vertical stand 2 andshort and curve tube 11 integrating the support 8 can be introduced.

Regardless of the type of assembly (by vertical stand 2 or support 8),the structure and form of functioning of the device for drying hairherein remain unaltered in its main version.

FIG. 4 of the present patent allows the observation of the inferior faceof the structure 5 of the appliance 1, wherein its physical embodimentcan be better understood, which is defined by a hollow central portion12, from which equally hollow tentacle structures 13 substantiallyderive, wherein the inferior face 14 of the hollow central portion 12has continuity in the internal face 15 of the equally hollow tentaclestructures 13, thus forming a continuous and involving surface, which isprovided with a multiplicity of beaks 16, through which the air jets areprojected.

The hollow structure 5 is defined so that both its hollow centralportion 12 and its equally hollow tentacle structures 13 configure aninvolving space E inside which the user's head of the device for dryinghair 1 will be positioned. As can be easily noticed by observing thefigures illustrating the present patent, as equally hollow tentaclestructures 13 present different length measures, wherein the shortestones are in the frontal region of the device for drying hair 1, whilethe longest ones are in the side and posterior regions of saidappliance.

FIG. 5 illustrates a schematic section of the structure 5 of the devicefor drying hair herein, where the positioning of the electric hair dryermanual 7 can be noticed, which is assembled by fitting the nozzle 6,

The handheld hair dryer 7 is used to provide a constant air flow (heatedor not) to hollow structure 5, being said constant air flow b (indicatedby arrows A) is equally distributed by the interior of the hollowstructure 5 occupying the central portion 12 and also reaching theinternal region of the tentacle structures 13, being said air flow Athen distributed through beaks 16, which, due to its orientation,project the air flow A to the center of the involving space E.

FIG. 6 illustrates the device for drying hair 1 according to a variationwherein the spaces between the hollow tentacle structures 13 receive orare able to embody corresponding closure pieces 17 which can beassembled by simple pin fitting 18 into holes 19 provided in thestructure 5.

The closure pieces 17 can be produced in transparent material, or anyother appropriate having the function of establishing a relative closureof space E, thus limiting the transference of heated air to the externalenvironment to the device for drying hair 1.

The fact that the closure pieces 17 are transparent allows theprofessional tracking the drying to check how the process is going.

FIG. 7 illustrates another variation, wherein the closure pieces 17 canbe pivoted around a upper axis 20, which allows the eventualtransference of hot air to the external environment may be properlycontrolled, i. e., said closure pieces being totally aligned with thespaces between the hollow tentacle structures 13 occurring a larger heatconcentration, while if such closure pieces 17 are in an intermediatepositioning, condition depicted in FIG. 7, there will be less heatconcentration.

The concept that characterizes the device for drying hair 1 may,alternatively, serve as base for the creation of an appliance that doesnot rely on use of a handheld hair dryer 7 to provide hot (or cold) airflow. In this case, the base of the hollow structure 5 can be superiorlyelevated to embody in its interior the conventional components of a hairdryer, i. e., a motor/rotor set and at least an electric resistanceunit.

FIGS. 8 and 9 illustrate a modality of hair dryer based on the devicefor drying hair 1, wherein said modality of hair dryer is indicated byreferral number 21.

The hair dryer 21 is provided with a hollow structure 5 which comprisesa posterior projection 9, from which a coupling terminal is developed10, wherein, by simple fitting, both upper end of the vertical stand 2and, alternatively, short and curve tube 11 integrating the support 8can be introduced.

From the inferior face of the structure 5 of the hair dryer 21, which isdefined by a hollow central portion 12, derive, in a substantiallyradial way, equally hollow tentacle structures 13, wherein the inferiorface 14 of the hollow central portion 12 has continuity in the internalface 15 of the equally hollow tentacle structures 13, thus forming acontinuous and involving surface in the same patterns of the device fordrying hair 1, which is provided with a multiplicity of beaks 16,through which the air jets are projected.

The hollow structure 5 of the hair dryer 21 is defined as both hollowcentral portion 12 and equally hollow tentacle structures 13 configurean involving space (E) inside which the user's head of the hair dryer 21is positioned.

The equally hollow tentacle structures 13 present different lengthmeasures, wherein the shortest ones are in the frontal region of thedrying hair 1, while the longest ones are in the side and posteriorregions of said hair dryer, which is superiorly elevated to embody inits interior the conventional components of a hair dryer, i. e., amotor/rotor set and at least an electric resistance unit.

It must be stressed that the internal construction of the hair dryer 21as depicted in FIGS. 6 and 7 does not require more explanation, sincethe type of project solution to make the assembly of its main componentsviable (motor/rotor set and electric resistance) are well known by thoseskilled in the art, thus not demanding special projects for suchpurposes. Thus, for effect of illustration, the hair dryer 21 is part ofthe basic project of the hollow structure 5 of the device for dryinghair 1.

The versions of the hair dryer 21 herein may foresee both the versionwith vertical stand 2 and the version incorporating the support 8.

The internal structure of said hair dryer 21 regarding the distributionof air flow in its interior follows the same solution already depictedand described regarding the device for drying hair 1.
